Product Details
Choose from a wide range of individually calibrated plain form models measuring the relative density (specific gravity) of oil and petroleum-related products in various ranges from -1° to 91° API, in accordance with the American Petroleum Institute (API) and American Society of Testing Materials (ASTM) E100 standards. These hydrometers conform to the accuracy requirements of ASTM hydrometers and are calibrated traceable to NIST standards at three points, supplied with a detailed calibration report stating corrections to one-tenth of the smallest division. Each hydrometer measures 330mm (13") long, features lead-free ballast and glass, and is individually serialized. The temperature standardization is set at 60°F/60°F. Each unit is calibrated and hand inspected by the U.S. quality team in an exclusive triple accredited/registered ISO/IEC 17025:2017 and A2LA accredited calibration laboratory, which is internationally recognized and accepted by the signatory economies of the ILAC/MRA, and located in an ISO 14001:2015 environmental management system registered facility. The hydrometers are packaged in a recyclable, deluxe storage box and are made in the U.S.A. Note that ASTM calibrated hydrometers should be stored in a clean, dry, safe place and should not be subjected to extreme temperatures.
